Okies, I'm mixing 5mg with 32oz of water, even though the directions say to mix it with 12oz. I can't fathom that'd be a problem. Besides, I drink my water out of a 32oz bottle (4/day at present).
I may just mix it with my protein drinks tomorrow. Don't think that matters either. Can't imagine the saturation level of it in a drink would impact the amount ingested at all. Just makes it mix easier to use more fluid.
